How to Unlock the Blank Collar in Mewgenics (Step-by-Step)

• Key Item: The Blank Collar (Allows for duplicate classes in a single run).
• Unlock Requirement: Locate Tracy on the NPC map and trade in cats aged 5+.
• Cost & Milestones: 150 coins for the first collar (after 10 cats); max of 3 collars available (after 40 cats each).
• Utility: Randomly assigns a class to bypass the "one of each" restriction.
• Strategy: Use Thief or Druid classes to farm the gold needed for shop purchases.

Breaking the Class Ceiling: Why the Blank Collar Matters

In the brutal tactical landscape of Mewgenics, your team composition is everything. We’ve all been there: you have two cats with god-tier stats for the Hunter class, but the game’s hard restriction on unique roles forces you to sideline one. It’s a frustrating bottleneck for anyone trying to min-max their way through a run. This is where the Blank Collar comes in—it’s not a perfect fix, but for players looking to break the meta and stack duplicate classes, it’s the only game in town.

How to Unlock Tracy and the Trade-In System

You can’t just find the Blank Collar in a chest; you have to earn it through some rather cold-blooded management. First, you need to unlock Tracy, a vendor found early on the NPC map. Tracy doesn’t deal in standard currency for her unlocks—she wants your veterans.

To get her shop functional, you’ll need to send her cats that are at least 5 years old. Our take? Don't get too attached. The first cat you send opens up food box upgrades, but the real grind starts after that.

The Unlock Progression

• The First Collar: Once you’ve sent 10 old cats to Tracy, she will stock the first Blank Collar for 150 coins.
• The Long Game: Every subsequent 40 cats sent to Tracy unlocks an additional collar, capping out at three.
• Availability: Tracy’s shop is subject to RNG. She won’t always have the collar in stock, so we recommend checking back every time the shop restocks to ensure you don’t miss a window.

Mastering the RNG: How the Blank Collar Functions

If you were hoping the Blank Collar would let you manually pick a second Fighter, we have some bad news. The item operates on a "random roll" basis. When you enter the Collar select screen, the Blank Collar will automatically roll into a random class role.

While this sounds chaotic, the math favors the prepared. Once you’ve unlocked all three collars, your statistical probability of hitting a duplicate class for your specific team build increases significantly. It’s about flattening the randomness of a roguelike and seizing as much control as the game allows. If you’re lucky, you can even stack three of the same class for a truly specialized (and likely broken) run.

Pro-Tip: Farming the 150 Coin Buy-In

150 coins isn't pocket change in the early game. If you're struggling to fund your collar addiction, we suggest running a Thief. Focus on abilities that scatter coins or allow you to pickpocket enemies directly. By the time you hit the third zone, you should have more than enough to clear out Tracy’s inventory. Alternatively, the Druid’s raccoon transformation is a solid QoL choice for vacuuming up floor items and extra loot.

Final Verdict

The Blank Collar system is a classic Edmund McMillen design: it’s a bit grindy, highly reliant on RNG, but ultimately essential for high-level play. While it won't fundamentally rewrite the game's difficulty, it provides that vital layer of flexibility needed for the toughest raids. If you want to stop playing by the game’s "one class" rules, start sending your old cats to Tracy immediately.
